Three new triterpene oleanane glycosides, melilotosides A1, B1, and C1, and non-glycosylated soyasapogenol B were isolated from Melilotus officinalis (L.) Pall. (Fabaceae) roots. The structures of the glycosides were proved using chemical transformations and spectral data. Melilotoside A1 is soyasapogenol B 3-O-β-Dxylopyranoside; melilotoside B1, soyasapogenol B 3-O-[β-D-galactopyranosyl-(1-2)-β-D-xylopyranoside]; melilotoside C1, soyasapogenol B 3-O-[α-L-rhamnopyranosyl-(1-2)-β-D- galactopyranosyl(1-2)-β-Dxylopyranoside].

Eight steroidal glycosides, tentatively named glycosides A(1), B(2), C(3), D(4), E(5), F(6), G(7) and H(8), were isolated from the methanol extract of the subterranean part of Liriope platyphylla Wang et Tang (Liliaceae).The structures of these glycosides were established as ruscogenin 3-O-α-L-rhamnopyranoside (1), 25(S)-ruscogenin 1-O-β-D-fucopyranosido-3-O-α-L-rhamnopyranoside (2), 25(S)-ruscogenin 1-O-α-L-rhamnopyranosyl-(1->2)-β-D-fucopyranoside (3), ruscogenin 3-O-β-D-glucopyranosyl(1->3)-α-L-rhamnopyranoside (4), a mixture of 3-O-2)>3)>-β-D-glucopyranosides of diosgenin and yamogenin (=a mixture of ophiopogonin D' and its 25(S)-isomer, 5), a mixture of 3-O-β-chacotriosides of diosgenin and yamogenin (= a mixture of dioscin and its 25(S)-isomer, 6), ruscogenin 1-sulfate 3-O-α-L-rhamnopyranoside (7), and 26-O-β-D-glucopyranosyl-22-O-methylfurost-5-ene-3β,26-diol 3-O-β-chacotrioside (=methyl proto-dioscin, 8).
